TOOL.

Specification of Letters Patent.

Patented Dec. 28, 1909.

Application filed April 25, 1908. Serial No. 429,148.

To all whom it may concern: 1 1

Be it known that I, GEORGE A. BARNns, a citizen of the United States,residing at New Haven, in the county of New Haven and State ofConnecticut, have invented certain new and useful Improvements in Tools,of which the following is a specification, reference being had thereinto the accompanying drawings.

My invention relates to new and useful improvements in tools, referringmore particularly ,to that class of lathe tools known as a side tool,and has for its object, among other things, to produce an economicaltool of this character that will be rigid while in operation and havinga cutter therein that is separably and adjustably secured to the body,with ample clearance for the cutting edge.

T 0 these, and other ends, my invention consists in the tool havingcertain details of construction and combinations of parts, as will behereinafter described and more particularly pointed out in the claim.

Referring to the drawings, in which like numerals of reference designatelike parts in the several figures: Figure l is a plan of my improvedtool; Fig. 2 is a side elevation thereof; Fig. 3 is an elevation of thefront end; and Fig. f is a transverse section upon line ;\:'B of Figs. 1and 2.

In the practice of my invention I provide a body member 1 having in oneend thereof a slot 2 which lies at an angle to the sides and bottomthereof (see Figs. 3 and 4) and also at an angle from the front to therear (see Figs. 1 and 2). The side and front edges of this slot as itopens through 1 the top of the tool are adjacent to the side and frontedges of the body member. Movably mounted within this slot is the cutter3 which is preferably made from a piece of flat bar steel of standardsize with the ends beveled at l to provide a cutting edge. Threadablethrough the lug 5 integral with the body is a screw 6, the end of whichinipinges against the edge of said cutter and rigidly holds the samewithin said body. The angle of the slot 2 within which the cutter isheld is such that the side and end thereof overhang the body and engagethe work with a clearance suflicient to make agood cutting edge.

Having descrlbed my invention, what I claim as new and desire to secureby Letters Patent, is

A lathe tool, comprising in combination, a body member having a cuttersocket rectangular in cross section formed by an open ing provided inone end of said body, at an angle to the sides and bottom and projectingdownwardly and rearwardly from the top of the body, a cutter comprisinga flat strip of metal conformably fitted in the socket, said strip ofmetal having an upper cutting edge, a lug integral with the body andprojecting upwardly from the top thereof, and a screw projecting throughsaid lug at an angle thereto to impinge against the cutter.

In testimony whereof I my signature in presence of two witnesses.
